Engineering Solutions for the Long Haul.

Since it was founded back in 1916, Deuchler has been defined by responsiveness and its ability to solve problems. Like the generations before us, Deuchler helps clients and communities like yours plan, build, repair and renew their structures and systems for the long haul.

We make your needs our highest priorities for one simple reason. We live and work in the communities you’re in so every project is treated as if it was being done for a friend or neighbor.

When your needs change (growth, environmental requirements, etc.), we can help then, too. In 1996 for instance, our clients were facing increasingly complex EPA and other environmental regulations. In response, Deuchler developed an environmentally-focused group with engineers, geologists, biologists and other specialists with the knowledge to guide in all ways.

Or adding an electrical engineering team whose understanding of constantly changing technologies can support your design, construction and control systems from start to finish. Whether your project is a limited engagement or a multi-year endeavor, Deuchler can deliver for you. Need proof? Almost all of our projects come from referrals and with very few exceptions, almost every client has engaged Deuchler on multiple projects after initial engagement.

Our Mission and Commitment to You

As it was from our inception over 100 years ago, the Deuchler team believes that treating people right and being passionate about making a difference in their lives, is everything.

As technology has rapidly changed and the delivery of services has increased even more so, our commitment to being there for clients like you, has grown with it.

Today, clients are able to better visualize project outcomes through Deuchler’s innovative offerings like 3-D modeling and rendering.

In Illinois, energy and conservation groups are increasingly tightening their restrictions on natural resources. Deuchler is passionate about helping its clients in areas like “Net Zero” water policies where water is treated and returned back to the same watershed as it came from.

Clients dealing with regulatory water policies as well as natural occurrences like droughts find relief from Deuchler’s considerable knowledge and desire to bring “toilet to tap” resourcefulness to everyone it serves. What does tomorrow hold? While hard to predict, one thing is certain. Our team will remain ahead of the curve for you, providing all the knowledge and resources you need.

Leadership Team

Passionate and dedicated to you, Deuchler’s team is constantly looking to find the solutions that can impact your group’s success.

Mark HalmMark Halm
Vice President

While in grade school in the 1970’s, Mark Halm became inspired to become a protector of the environment. He earned his bachelor and master’s degrees in Civil and Environmental Engineering from Marquette University and a master’s degree in business administration from Keller Graduate School of Management.

In 2012, Mark became certified by the American Academy of Environmental Engineers with a specialization in water supply and wastewater.

Mark joined Walter E. Deuchler Associates, Inc. in 2001 and became a principal in 2006. He wears many hats but foremost are project management and technical supervision for wastewater planning, design and construction projects. This includes: defining specific tasks, scheduling and coordinating personnel and resources, and evaluation of progress and quality.

Mr. Halm has recently managed planning, design and construction of wastewater treatment facility improvements for the Fox Metro WRD, City of Plano, Salt Creek Sanitary District, Village of Addison and more. His 25+ years of experience is instrumental in delivering successful projects to Deuchler’s clients.

Today, Mr. Halm is a recognized leader in the wastewater industry serving in the past as an Executive Board Member of the Illinois Water Environment Association (IWEA) and a delegate to the Water Environment Federation (WEF). Currently, Mark serves on IWEA’s Nutrient Removal and Recovery Committee (former chair), program, LIFT and public education committees.

Of all of these activities however, Mr. Halm receives the most satisfaction from judging local science fairs, encouraging the next generation to pursue careers in the water environment industry. Mr. Halm will be also serving a three-year term on Marquette University’s Civil, Construction, and Environmental Engineering Academic Advisory Panel.
